Agilent 0.6 Amp Output Current IGBT Gate Drive Optocoupler Data Sheet HCPL-3150 (Single Channel) HCPL-315J (Dual Channel) Description The HCPL-315X consists of a LED optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by this optocoupler makes it ideally suited for directly driving IGBTs with ratings up to 1200 V/50 A. For IGBTs with higher ratings, the HCPL-3150/315J can be used to drive a discrete power stage which drives the IGBT gate.

Applications Information Eliminating Negative IGBT Gate Drive To keep the IGBT firmly off, the HCPL-3150/315J has a very low maximum VOL specification of 1.0 V. The HCPL-3150/315J realizes this very low VOL by using a DMOS transistor with 4 (typical) on resistance in its pull down circuit. When the HCPL-3150/315J is in the low state, the IGBT gate is shorted to the emitter by Rg + 4 . Minimizing Rg and the lead inductance from the HCPL-3150/ 315J to the IGBT gate and emitter (possibly by mounting the HCPL-3150/315J on a small PC board directly above the IGBT) can eliminate the need for negative IGBT gate drive in many applications as shown in Figure 25. Care should be taken with such a PC board design to avoid routing the IGBT collector or emitter traces close to the HCPL-3150/315J input as this can result in unwanted coupling of transient signals into the HCPL-3150/315J and degrade performance. (If the IGBT drain must be routed near the HCPL3150/315J input, then the LED should be reverse-biased when in the off state, to prevent the transient signals coupled from the IGBT drain from turning on the HCPL-3150/315J.)

(Discussion applies to HCPL-3120, HCPL-J312 and HCNW3120) Step 1: Calculate Rg Minimum from the IOL Peak Specification. The IGBT and Rg in Figure 26 can be analyzed as a simple RC circuit with a voltage supplied by the HCPL-3150/315J. (V CC - VEE - VOL) Rg ------------------------ IOLPEAK (V CC - VEE - 1.7 V) = -------------------------- IOLPEAK (15 V + 5 V - 1.7 V) = -------------------------- 2.5 A = 30.5 14 The VOL value of 2 V in the previous equation is a conservative value of VOL at the peak current of 0.6A (see Figure 6). At lower Rg values the voltage supplied by the HCPL-3150/315J is not an ideal voltage step. This results in lower peak currents (more margin) than predicted by this analysis. When negative gate drive is not used VEE in the previous equation is equal to zero volts. PT = PE + PO PE = I F * VF * Duty Cycle PO = PO(BIAS) + PO (SWITCHING) = ICC * (VCC - VEE) + ESW(RG, QG) * f For the circuit in Figure 26 with IF (worst case) = 16 mA, Rg = 30.5 , Max Duty Cycle = 80%, Qg = 500 nC, f = 20 kHz and TA max = 90C: PE = 16 mA * 1.8 V * 0.8 = 23 mW Step 2: Check the HCPL-3150/ 315J Power Dissipation and Increase Rg if Necessary. The HCPL-3150/315J total power dissipation (PT ) is equal to the sum of the emitter power (PE) and the output power (PO): PO = 4.25 mA * 20 V + 4.0 J* 20 kHz = 85 mW + 80 mW = 165 mW > 154 mW (PO(MAX) @ 90C = 250 mW-20C* 4.8 mW/C) HCPL-3150 +5 V 8 1 270 0.1 F 2 + - VCC = 15 V + HVDC 7 Rg Q1 CONTROL INPUT 6 3 - + 74XXX OPEN COLLECTOR 4 VEE = -5 V 3-PHASE AC 5 Q2 - HVDC Figure 26a.

Since P O for this case is greater than P O(MAX), Rg must be increased to reduce the HCPL3150 power dissipation.

Thermal Model (HCPL-3150) The steady state thermal model for the HCPL-3150 is shown in Figure 28a. The thermal resistance values given in this model can be used to calculate the temperatures at each node for a given operating condition. As shown by the model, all heat generated flows through qCA which raises the case temperature TC accordingly. The LD = 439C/W TJE TJD LC = 391C/W DC = 119C/W TC CA = 83C/W* TA Figure 28a. Thermal Model. 16 value of qCA depends on the conditions of the board design and is, therefore, determined by the designer. The value of qCA = 83C/W was obtained from thermal measurements using a 2.5 x 2.5 inch PC board, with small traces (no ground plane), a single HCPL-3150 soldered into the center of the board and still air. The absolute maximum power dissipation derating specifications assume a qCAvalue of 83C/W. From the thermal mode in Figure 28a the LED and detector IC junction temperatures can be expressed as: TJE = PE * (qLC||(qLD + qDC) + qCA) TJE = PE * (230C/W + qCA ) + PD * (49C/W + qCA) + TA TJD = PE * (49 C/W + qCA) + PD * (104 C/W + qCA) + TA For example, given PE = 45 mW, PO = 250 mW, TA = 70C and qCA = 83C/W: TJE = PE* 313C/W + PD* 132C/W + TA = 45 mW* 313C/W + 250 mW * 132C/W + 70 C = 117 C TJD = PE* 132C/W + PD* 187 C/W + TA = 45 mW* 132C/W + 250 mW * 187C/W + 70 C = 123 C TJE and TJD should be limited to 125C based on the board layout and part placement (qCA) specific to the application. qLC * qDC + PD * (---------------------- + qCA) + TA qLC + qDC + qLD qLC * qDC TJD = PE (-------------------- +q ) qLC + qDC + qLD CA + PD* (qDC||(qLD + qLC) + qCA) + TA Inserting the values for qLC and qDC shown in Figure 28 gives: TJE = TJD = TC = qLC = qLD = qDC = qCA = LED junction temperature detector IC junction temperature case temperature measured at the center of the package bottom LED-to-case thermal resistance LED-to-detector thermal resistance detector-to-case thermal resistance case-to-ambient thermal resistance *qCA will depend on the board design and the placement of the part.

CMR with the LED On (CMRH) A high CMR LED drive circuit must keep the LED on during common mode transients. This is achieved by overdriving the LED current beyond the input threshold so that it is not pulled 18 Esw - ENERGY PER SWITCHING CYCLE - J LED Drive Circuit Considerations for Ultra High CMR Performance Without a detector shield, the dominant cause of optocoupler CMR failure is capacitive coupling from the input side of the optocoupler, through the package, to the detector IC as shown in Figure 29. The HCPL3150/315J improves CMR performance by using a detector IC with an optically transparent Faraday shield, which diverts the capacitively coupled current away from the sensitive IC circuitry. How ever, this shield does not eliminate the capacitive coupling between the LED and optocoupler pins 5-8 as shown in Figure 30. This capacitive coupling causes perturbations in the LED current during common mode transients and becomes the major source of CMR failures for a shielded optocoupler. The main design objective of a high CMR LED drive circuit becomes keeping the LED in the proper state (on or off) during common mode transients. For example, the recommended application circuit (Figure 25), can achieve 15 kV/s CMR while minimizing component complexity. not recommended for applications requiring ultra high CMRL performance. Figure 33 is an alternative drive circuit which, like the recommended application circuit (Figure 25), does achieve ultra high CMR performance by shunting the LED in the off state. 7 Qg = 100 nC 6 Qg = 250 nC Qg = 500 nC 5 VCC = 19 V 4 VEE = -9 V 3 2 1 0 0 20 40 60 80 100 Rg - GATE RESISTANCE - Figure 27.

A minimum LED current of 10 mA provides adequate margin over the maximum IFLH of 5 mA to achieve 15 kV/s CMR. CMR with the LED Off (CMRL) A high CMR LED drive circuit must keep the LED off (VF VF(OFF)) during common mode transients. For example, during a -dVCM /dt transient in Figure 31, the current flowing through CLEDP also flows through the RSAT and VSAT of the logic gate. As long as the low state voltage developed across the logic gate is less than VF(OFF), the LED will remain off and no common mode failure will occur. The open collector drive circuit, shown in Figure 32, cannot keep the LED off during a +dVCM/dt transient, since all the current flowing through CLEDN must be supplied by the LED, and it is Under Voltage Lockout Feature The HCPL-3150/315J contains an under voltage lockout (UVLO) feature that is designed to protect the IGBT under fault conditions which cause the HCPL-3150/315J supply voltage (equivalent to the fully-charged IGBT gate voltage) to drop below a level necessary to keep the IGBT in a low resistance state. When the HCPL-3150/315J output is in the high state and the supply voltage drops below the HCPL-3150/315J VUVLOthreshold (9.5
